Fluoridated milk, preferably containing up to two parts per million by weight of sodium fluoride, may be prepared by causing a stream of non-fluoridated milk to mix with a stream of high-concentration fluoridated milk at such flow rates that the resulting mixture contains the required fluoride concentration. A suitable apparatus for the process is shown in Fig. 1 and comprises a bulk milk tank 6 and smaller tank 10 for the high concentration fluoridated milk, the outlet of these tanks merging into a common outlet to enable the non-fluoridated and high concentration fluoridated milks to mix. An alternative apparatus (Fig. 2, not shown) comprises first and second bulk milk tanks 40 and 41 of equal capacity, first and second smaller tanks 62 and 63 of equal capacity each associated with one of the bluk tanks, the bulk tanks having common inlet and outlet. valves 45 and 52 respectively, said valves operable in such a manner. as to allow one bulk tank and smaller tank system to fill whilst the other system discharges, and vice versa. Each smaller tank has an inlet from a tank containing high concentration fluoridated milk, thus enabling milk from the appropriate bulk tank to be sufficiently diluted with the fluoride compound.

A metal piston ring assembly, Fig. 3, consists of an outer ring 10 which is made of a selflubricating metallic substance, such as pressure fitted powdered metal and dry lubricant, and is retained in a groove in a substantially U-shaped steel or cast-iron bearing ring 12, the bearing ring groove and that part of the ring 10 engaging therein each have an outer section which widens conically as seen in cross-section. The ring 10 has an outer portion 23 which in operation projects above the outer periphery of the ring 12 and has radial side walls 24 and an outer periphery having a grooved cylindrical portion 28 and bevelled portions 27. Two or more piston rings may be mounted in an annular piston groove 30 bounded by co-operating parts 31, 32 of the piston. The grooves of each bearing ring 12 may be offset from the bearing ring central axis 33 so that the lateral sides 24 of the rings 10 are close to each other. Shoulders 34 in the groove 30 prevent excessive spread of the rings 12 where the rings 10 are worn. Rotation of the piston rings is prevented by pins 45 in the piston, Fig. 9, engaging recesses 46 in the bearing rings 12. The ends of the bearing ring 12 overlap, one end being formed with a rebate 37 having a projection 38, Fig. 4, which engages in a peripheral recess 39, Fig. 7, in the other end and, when the outer ring 10 becomes worn, bears against the end wall 41 of the recess to limit the spread of the bearing ring.

Abstract: 1360988 Gas manufacture I G NIXON 22 Dec 1971 [25 Sept 1970] 45722/70 Heading C5E A hydrocarbon fuel, e.g. heavy fuel oil, is reacted with molecular oxygen in a burner to produce a chemically reducing gaseous mixture, the reactants being surrounded in the burner by a coaxial mantle of cooling gases which may have a rotary motion, produced by mixing a hydrocarbon, e.g. a light petroleum fraction, with a gas containing carbon dioxide and/or water vapour, e.g. top gas from a blast furnace or other iron ore reduction plant. The reactants may be mixed with the cooling gases before leaving the burner to form a product gas. After leaving the burner the product gas may be passed over a catalyst, e.g. a nickel compound, to increase its reducing properties. The catalyst may be regenerated by top gas from a blast-furnace or other iron ore reduction plant at above 700 C. The temperature of the product gas may be regulated to about 1200 to 1400 C. The hydrocarbon may contain 1 to 13 carbon atoms, e.g. natural gas. The cooling gases may have an oxygen balance higher, and the reactants an oxygen balance lower, than that required for optimum autogeneous reaction. The hydrocarbon and the gas containing carbon dioxide and/or water vapour may be heated to above 300 C. before mixing or may be heated before or after mixing to 700 to 1200 C. The reducing product gas may be fed to an iron ore reduction plant. As shown, fuel oil is supplied via heater 25 to fuel inlet 18 of the burner 10; oxygen is supplied via heater 28 to oxygen inlet 15; natural gas is supplied via heater 31, valve 33, and manifold 34 to annular conduit 20 which surrounds the burner body 11; blast furnace top gas is supplied via blower 37, heater 38 and either via valves 40, 33 and manifold 34 to annular conduit 20, or via valves 43, 45, catalyst chambers 44, 46, valves 47, 48 and manifold 34 to annular conduit 20. The catalyst chambers are used alternately. Product gas from the burner may be supplied to the catalyst chambers via line 51 and valves 57, 58 and the partially combusted gas is fed via outlet lines 59, 60, 61 and valves 62, 63, to a blast furnace. In the burner, fuel from jet 19 mixes with oxygen from ports 17 and ignites with a short flame cone at burner throat 14 and in space 50. Top gas and natural gas mix in pipe-line 35 and annular conduit 20, enter annular space 22 between shroud 13 and casing 12 via nozzles 21, to sweep the burner casing 12, thus shielding the casing from the hot combustion gases prior to mixing and reacting with the combustion gas to form the product gas.

Apparatus for producing tear-strips from an elongate web 1, Fig. 1, of material of width equal to the desired length of the tear-strips to be produced, comprises feed rollers 3 to advance the web between a pair of knives 5, 7, operable transversely of the direction of advance of the web, and a conveyer to receive and remove the strips from the knives. The feed rollers operate incrementally to advance an appropriate amount of tear-strip material. The knife 7 effects a progressive cut, starting at the downstream edge of the web (relative to the conveyer movement). As it is severed the strip is blown upwards by an air-blast from apertures in the upper surface of the knife 7, which are supplied, via a pipe 12, with compressed air. Above the knife 7 is the lower run 13, Fig. 2, of an air-pervious conveyer belt 14 arranged with a suction box 16, so that the severed strip is held against the belt 14. A wrapper web 17 is fed from a reel 18, around a guide roller 19 and is supplied with a line of adhesive by a wheel 20 fed from a gum pot 21 via a wick 22. Thus the strip adheres to the wrapper web as it is pressed against the roller 15. A heater 23 may be provided to dry the gum. In a second similar embodiment, the wrapper material is applied above the tear-strip, and cutting is effected by a pivoted scissorstype blade. A suction drum may be used in place of the pervious belt, in which ease the fixed and movable blades are curved to allow for the curvature of the drum. Alternatively, an electrostatic charge may be directly applied to, e.g. a nylon conveyer belt, or a nylon belt may acquire sufficient charge, as a result of movement, to cause adherence of the tearstrips during their transfer to the wrapper web. The intermittent incremental movement of the rollers, which feed the tear-strip web, may be obtained by a system of ratchets and pawls, fine adjustment being effected by releasing the upper roller by operation of a handle, cams and bell-crank lever arrangement.
